[MQ 9.3.0.5 Apr 2023]

What's changed in IBM MQ 9.3.0 Fix Pack 5

IBM® MQ 9.3.0 Fix Pack 5 includes a resource change.

New OAMLdapResponseWarningTime parameter in TuningParameters stanza of qm.ini

If a connection to an LDAP server took longer than the threshold number of seconds specified by the OAMLdapResponseWarningTime parameter, then an AMQ5544W message will be written to the error log. For more information, see TuningParameters stanza of the qm.ini file.

Change to RPM signature version

The RPM signature version was changed to v4 at IBM MQ 9.3.0 Fix Pack 5 for Long Term Support. As part of this, the private key used by IBM to sign the packages was changed, and so if you want to validate RPM packages at or above these levels, you need to import the newer IBM MQ public signing gpg key. You will also need the old key if you want to retain the ability to verify the signatures on older IBM MQ 9.3.x packages. For more information, see IBM MQ code signatures.
